1. Determining the Drift in Reinforced Concrete Building Using ANFIS Soft Computing Modeling

Hojjatollah Torkian; Zahra Keshavarz

Volume 1, Issue 1 , Winter 2018, Pages 1-11


  Earthquakes are considered as one of the most significant natural disasters that can potentially cause significant damages to structures. Displacement of buildings’ floors is one of the serious failures in structures caused by earthquakes. In this paper, the drift of a concrete frame with the shear ...  Read More

2. Numerical Simulation of Concrete Mix Structure and Detection of its Elastic Stiffness

Mofid Mahdi; Iqbal Marie

Volume 1, Issue 1 , Winter 2018, Pages 12-22


  Concrete mix stiffness (CM) primarily relies on its ingredients, which mainly consists of stone aggregate and mortar. To analyse the role of the components of CM on its properties a numerical simulation of CM structure is conducted. Within the scope of this study, the structure and the properties of ...  Read More

3. Reliability-Based Investigation on Compressive Strength Characteristics of Structural-Sized Iroko (Meliceae Excelsa) and Mahogany (Khaya Ivorensis) Timber Column Found in Nigeria

Abdullahi Alao Jimoh; Rauf Rahmon; Sofiyyat O. Ajide

Volume 1, Issue 1 , Winter 2018, Pages 23-37


  This research work examined the reliability of the Nigerian grown Iroko and Mahogany timber species as column materials. The strength and physical properties of these timber species were determined to predict the suitability of the species as structural material. Forty lengths of timber species of 50mm ...  Read More

4. Seismic Fragility Assessment of Local and Global Failures in Low-rise Non-ductile Existing RC Buildings: Empirical Shear-Axial Modelling vs. ASCE/SEI 41 Approach

Mohammad Reza Azadi Kakavand; Mohammad Khanmohammadi

Volume 1, Issue 1 , Winter 2018, Pages 38-57


  The brittle behavior of older non-ductile reinforced concrete buildings such as shear-axial failure in columns can cause lateral instability or gravity collapse. Hence, the attempt is to assess the collapse potential through fragility curves. Current research focuses on fragility assessment of these ...  Read More

5. The Effect of Diagonal Stiffeners on the Behaviour of Stiffened Steel Plate Shear Wall

Behtash Amiri; Hamed AghaRezaei; Reza Esmaeilabadi

Volume 1, Issue 1 , Winter 2018, Pages 58-67


  In the current study, the nonlinear behavior of the stiffened steel plate shear wall with diagonal stiffeners is numerically studied. After nonlinear pushover analysis, the finite element modeling results are compared with un-stiffened and stiffened steel plate shear walls, with the horizontal and vertical ...  Read More

7. Flow and Pollutant Dispersion Model in a 2D Urban Street Canyons Using Computational Fluid Dynamics

Zahra Jandaghian

Volume 1, Issue 1 , Winter 2018, Pages 83-93


  A two-dimensional model is used to simulate temperature distribution, wind speed and pollutants dispersion within an isolated two-dimensional street canyon using SIMPLE algorithm in ANSYS Fluent version 16.2. The simulation is based on the Reynolds-averaged Navier–Stokes equations coupled with ...  Read More
